Wire crossover symbols for circuit diagrams. The CAD symbol for insulated crossing wires is the same as the older, non-CAD symbol for non-insulated crossing wires. To avoid confusion, the wire "jump" (semi-circle) symbol for insulated wires in non-CAD schematics is recommended (as opposed to using the CAD-style symbol for no connection), so as to avoid confusion with the original, older style ...
A less common symbol is simply a series of peaks on one side of the line representing the conductor, rather than back-and-forth. Wire crossover symbols for circuit diagrams. The CAD symbol for insulated crossing wires is the same as the older, non-CAD symbol for non-insulated crossing wires. To avoid confusion, the wire "jump" (semi-circle ...
Free version with unlimited schematic drawing and editing. Hierarchical schematics; Selection of colours for components, wires, etc. for easy identification. Zooming facility, auto-routing and snap-to-grid. Simple placement of components — select and click-to-place with mouse. Automatic repeat placement of last component.
A reference designator unambiguously identifies the location of a component within an electrical schematic or on a printed circuit board.The reference designator usually consists of one or two letters followed by a number, e.g. C3, D1, R4, U15.
A typical one-line diagram with annotated power flows. Red boxes represent circuit breakers, grey lines represent three-phase bus and interconnecting conductors, the orange circle represents an electric generator, the green spiral is an inductor, and the three overlapping blue circles represent a double-wound transformer with a tertiary winding.
Some graphics packages like Word Draw, Visio and AutoCad (lite) give more flexibility and resolution which is useful, for example when you need circuit symbols and general drawing on the same image. Also, there are many archive schematics around in Protel and it is good for doing complex circuits. - CPES 21:56, 10 Mar 2005 (UTC)
A power symbol is a symbol indicating that a control activates or deactivates a particular device. Such a control may be a rocker switch, a toggle switch, a push-button, a virtual switch on a display screen, or some other user interface. The internationally standardized symbols are intended to communicate their function in a language ...
It does not restrict symbols and connectors from various categories from being placed together. Dia has special objects to help draw entity-relationship models , Unified Modeling Language (UML) diagrams, flowcharts , network diagrams, and simple electrical circuits.
